At S8, the safety relay 55 is turned off.
If it is N, after the counter 52 and the timer 51 are reset, the counter 52 is counted once and the starter motor 29 is driven (S12 to S15).

When the starter motor 29 is driven, the engine start determination circuit 53 determines that the engine 9 has started (S16). When the start of the engine 9 is confirmed, the power supply to the starter motor 29 is stopped ( End).

Until the start of the engine 9 is confirmed in S16, the energization time to the starter motor 29 measured by the timer 51 is checked (S17). And
When the energizing time reaches 5 seconds, the timer 51 stops energizing the starter motor 29 (S18).

When the energization of the starter motor 29 is stopped in S18, the counter 52 checks the number of energizations of the starter motor 29 (S19), and when the number of energizations reaches 5, the starter motor 29 is energized. Ends (end).

If it is determined in S19 that the starter motor 29 is energized less than 5 times, the timer 51
Is reset (S20), the energization of the starter motor 29 is stopped, and an interval is provided. Then, the interval time measured by the timer 51 is collated (S21), and when the interval time reaches 10 seconds, the process returns to S13, and the starter motor 29 is energized again.

In the case of the engine starting device 26 configured as described above, at least one of the center stand 13 and the side stand 14 is used, and the engine can be started from a remote position except when the gear position is neutral. It will be impossible. Therefore, when the engine is started from a remote position, the motorcycle 1 is prevented from jumping out or falling.

In addition, whether the center stand 13 or the side stand 14 is used, it is possible to safely start the engine from a remote position.

Although the remote control means using radio waves is used in this embodiment, other remote control means using infrared rays or the like may be used. Further, the energization time, the interval time, and the number of energizations to the starter motor 29 at the time of starting the engine 9 are not limited to the numerical values in the present embodiment.
